Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional App. No. 60/964,103, filed Aug. 8, 2007.

BACKGROUND OF THE INVENTION

The present invention relates to a wafer probe for high frequency testing of integrated circuits and other electronic devices.

Integrated circuits (ICs) are economically attractive because large numbers of often complex circuits, for example microprocessors, can be inexpensively fabricated on the surface of a wafer or substrate. Following fabrication, individual dies, including one or more circuits, are separated or singulated and encased in a package that provides for electrical connections between the exterior of the package and the circuit on the enclosed die. The separation and packaging of a die comprises a significant portion of the cost of manufacturing a microelectronic device. To monitor and control the IC fabrication process and to avoid the cost of packaging defective dies, manufacturers commonly add electrical circuits or test structures to the wafer to enable on-wafer testing or “probing” to verify characteristics of the integrated circuits before the dies are singulated.

A test structure or device-under-test (DUT) typically comprises a simple circuit that includes a copy of one or more of the basic circuit elements of the integrated circuit, such as a single line of conducting material, a chain of vias or a single transistor. The circuit elements of the DUT are typically produced with the same processes and in the same layers of the fabrication as the corresponding elements of the marketable integrated circuits. Since the circuit elements of the DUT are fabricated with the same processes as the corresponding elements of the integrated circuits, the electrical properties of the DUT are expected to be representative of the electrical properties of the corresponding components of the integrated circuits. In addition to the DUT, test structures typically include a plurality of metallic contact or probe pads that are deposited at the wafer's surface and a plurality of conductive vias that interconnect the probe pads and the subsurface DUT. The performance of the test structure is typically tested by applying a test instrument generated signal to the probe pads and measuring the response of the test structure to the signal.

At higher frequencies, on-wafer characterization is commonly performed with a network analyzer. The network analyzer comprises a source of an AC signal, commonly a radio frequency (RF) or microwave frequency signal, that is transmitted to the DUT to produce a response. A forward-reverse switch directs the stimulating signals toward one or more of the probe pads of the DUT where a portion of the signal is transmitted to the DUT and another portion is reflected. Directional couplers or bridges pick off the forward or reverse waves traveling to and from the DUT. The waves are down-converted by intermediate frequency (IF) sections of the network analyzer where the signals are filtered, amplified and digitized for further processing and display. The result is a plurality of s-parameters (scattering parameters), the ratio of a normalized power wave comprising the response of the DUT to the normalized power wave comprising the stimulus supplied by the signal source.

The preferred interconnection between a network analyzer or other test instrument and a DUT is a wafer probe typically comprising a movable body that supports one or more contacts or probe tips that are arranged to engage a test structure's probe pad(s) on the surface of a wafer. Burr et al., U.S. Pat. No. 5,565,788, disclose a microwave probe comprising a support block which is attachable to a movable probe supporting member of a probe station. The support block supports a first end portion of a section of coaxial cable. The second end of the coaxial cable is freely suspended and, in turn, supports a probe tip section. Integrated circuits commonly utilize single ended or ground referenced signaling with a ground plane at the lower surface of the substrate on which the active and passive devices of the circuit are fabricated. Although there are a number of potential arrangements for the probe pads of a test structure that utilizes single-ended signaling, a common arrangement places a signal probe pad between a pair of spaced apart, grounded probe pads, a so-called ground-signal-ground (GSG) arrangement. The tip section of the microwave probe disclosed by Burr et al. includes a central signal conductor and one or more ground conductors generally arranged parallel to each other in a common plane to form a controlled impedance structure. The signal conductor is electrically connected to the inner conductor of a coaxial cable and the ground conductors are electrically connected to the outer conductor of the cable at the freely suspended end of the cable. A shield member is interconnected to the ground conductors and covers at least a portion of the signal conductor on the bottom side of the tip section. The shield member is tapered toward the tips with an opening for the tips of the conductive fingers. The signal conductor and the ground conductors each have an end portion extending beyond the shield member and, despite the presence of the shielding member, the end portions are able to resiliently flex relative to each other and away from their common plane so as to permit probing of devices having non-planar probe pad surfaces.

In another embodiment, Burr et al. disclose a microwave probe that includes a supporting section of coaxial cable including an inner conductor coaxially surrounded by an outer conductor. A tip section of the microwave probe includes a signal line extending along the top side of a dielectric substrate connecting a probe finger with the inner conductor of the coaxial cable. A metallic shield may be affixed to the underside of the dielectric substrate and is electrically coupled to the outer metallic conductor. Ground-connected fingers are placed adjacent the signal line conductors and are connected to the metallic shield by way of vias through the dielectric substrate. The signal conductor is electrically connected to the inner conductor and the ground plane is electrically connected to the outer conductor of the coaxial cable. The signal conductor and the ground conductor fingers (connected to the shield by vias) each have an end portion extending beyond the shield member and, despite the presence of the shielding member, the end portions are able to resiliently flex relative to each other and away from their common plane so as to permit devices having non-planar contact surfaces to be probed. While the structures disclosed by Burr et al. are intended to provide uniform results over a wide frequency range, they unfortunately tend to have non-uniform response characteristics at higher microwave frequencies.

Gleason et al., U.S. Pat. No. 6,815,963 B2, disclose a probe comprising a dielectric substrate that is attached to a shelf cut in the underside of the probe tip supporting portion of coaxial cable. The substrate projects beyond the end of the cable in the direction of the longitudinal axis of the cable. A signal trace is formed on the upper side of the substrate and conductively connects the center conductor of the coaxial cable with a via at the distal end of the signal trace, near the distal edge of the substrate. The via, passes through the substrate and conductively connects the signal trace to a contact bump or tip that will be brought into contact with a probe pad of the test structure to enable communication of a single-ended signal from the center conductor of the coaxial cable to the DUT. A conductive shield which is preferably planar in nature is affixed to the bottom surface of the substrate and electrically connected to the outer conductor of the coaxial cable. The conductive shield is typically coextensive with the lower surface of the substrate with the exception of an aperture encircling the contact tip for the signal trace. Contacts for contacting probe pads connected to the ground plane and spaced to either side of the signal probe pad of the test structure may also be provided. The conductive traces comprise a coplanar waveguide when the probe is operated at microwave frequencies.

At frequencies between DC and approximately 60 gigahertz (GHz), a coaxial cable is frequently preferred for communicating signals between the test instrumentation and the DUT. However, the central signal conductor of a coaxial cable is relatively small and, at microwave frequencies, skin effect restricts the current carrying area of the conductor to a thin layer at the conductor's surface. Heating of the dielectric separating the signal conductor and the coaxial ground conductor, may further impede the transmission of the signal. At frequencies greater than 40 GHz the probe and the test instrument are commonly interconnected with a waveguide. The waveguide comprises a hollow tube of conductive material, often rectangular in shape. Electromagnetic waves propagate in the waveguide channel by successive reflections from the inside surface(s) of the wall defining the waveguide channel. A waveguide is characterized by excellent isolation between signals and very low loss.

While a waveguide provides a low loss path for communicating signals between a probe and the related test instrumentation, the probes of Burr et al. and Gleason et al. rely on coaxial cable for connecting the waveguide and the probe tip. In addition to the reduced transmission efficiency of the coaxial cable resulting from skin effect and dielectric heating, the transition from coaxial cable to waveguide can be difficult and can introduce a substantial loss of signal. The transition from the waveguide to the coaxial cable is commonly accomplished by inserting the tip of the coaxial cable's center conductor into the interior of the waveguide and connecting the outer conductor to the wall of the waveguide. The projecting conductor acts as an antenna for the signals propagating in the waveguide. In a typical implementation a backshort, usually made of brass or some other reflective material and having a reflective face, is also included in the waveguide channel. The backshort is preferably located close to the projecting center conductor and typically oriented perpendicular to the waveguide channel so as to reflect any alternating signal present within the waveguide channel towards the projecting conductor. If properly positioned, the backshort will reflect the alternating signal within the waveguide into a standing wave pattern and signal degradation will be minimized in the transition from the coaxial cable to the waveguide. However, adjusting the position of the backshort relative to the center conductor of the coaxial cable to optimize performance in the primary band of the alternating signals, is often difficult and at high frequencies, very small deviations from the optimal position of the backshort may lead to significant signal degradation.

Katoh, U.S. Pat. No. 5,408,188, describes a wafer probe for high frequency single-ended signals in which a waveguide transitions directly to a coplanar line at the probe tip. The probe tip comprises a dielectric blade having a centrally located (laterally) signal conductor affixed to the lower surface of the blade. Ground conductors, spaced apart on either side of the signal conductor, are also affixed to the lower surface of the blade. The blade is clamped between separable upper and lower portions of the waveguide with the ground conductors in contact with the lower interior surface of the waveguide's wall. A stepped ridge affixed to the upper interior surface of the wall extends downward in the waveguide to approximately the level of the lower surface of the dielectric blade and the signal conductor which is affixed to the lower surface of the dielectric blade. The signal conductor is conductively interconnected with the downward projecting ridge. The high frequency waveguide probe enables probing with high frequency, single ended signals through the commonly utilized ground-signal-ground probe pad arrangement. However, the probe requires a special, split, waveguide section that includes a downwardly projecting ridge in the interior of the waveguide and, according to Katoh, the transition from the coplanar line of the probe tip to the waveguide can result in significant transmission losses.

While single-ended or ground referenced signaling predominates at lower frequencies, the integrity of single-ended signals is jeopardized at higher frequencies. Integrated circuits are fabricated by successive deposition of conductive, semi-conductive and insulating materials on a semi-conducting wafer and, as a result, electrical interconnections commonly exist between parts of the circuit's devices and between the devices and the substrate on which they are fabricated. These interconnections are commonly capacitive or inductive in nature resulting in frequency dependent parasitic impedances that make the true nature of ground referenced signals uncertain as the operating frequency of the circuit increases.

Referring to FIG. 9, a balanced device 100 comprises two nominally identical circuit halves 100A, 100B that are “virtually” grounded 104 at the symmetrical axis 102 of the two circuit halves. A balanced device outputs a differential mode signal comprising even and odd mode components of equal amplitude and opposite phase (So +1 and So −1) 106A, 106B when stimulated with a differential mode signal comprising even and odd mode components of equal amplitude and opposite phase (Si +1 and Si −1) 108A, 108B. The virtual ground is independent of the physical ground path of the IC and, at the operating frequency, the potential at the virtual ground does not change with time regardless of the amplitude of the stimulating signal. Balanced devices have become increasingly attractive as the operating frequencies of ICs have increased because the virtual ground enables balanced or differential circuits to tolerate poor RF grounding better than circuits operated with single-ended signals.

What is desired, therefore, is a low cost wafer probe enabling efficient communication of high frequency, differential signals between a DUT and a test instrument.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Integrated circuits (ICs) and other microelectronic devices are fabricated by successively depositing and etching layers of conductive, semi-conductive or insulating material on the surface of a wafer or substrate of semi-conducting material. Typically, the rear surface of the wafer, the back plane, is connected to a ground potential and signals are input to and output by the circuit through conductors that are deposited proximate the front surface of the wafer.

ICs are commonly inspected “on wafer” by measuring the response of one or more test structures when the structures are stimulated by a test signal. A test structure typically comprises a simple circuit or device under test (DUT) comprising one or more of the elements of the marketable integrated circuits. The devices of the DUT are typically fabricated with the same processes and in the same layers of the wafer fabrication as the corresponding element(s) of the integrated circuit. In addition, a test structure typically comprises a plurality of probe pads that are deposited on the surface of the wafer and conductively connected by a plurality of vias to the DUT which located below the surface.

Preferably, the test structure or other device under test is temporarily connected to test instrumentation by a probe assembly. The probe assembly typically comprises a probe body that is secured to a movable portion of a probe station which includes a mechanism for securing a wafer and moving the probe assembly in −x, −y, and −z directions to enable contacts on the probe to be brought into conductive engagement with the probe pads on the surface of the wafer. At frequencies in the radio and microwave frequency ranges, a network analyzer is commonly used to generate the test signal and measure the response of the DUT.

The test instrumentation is frequently connected to the probe by a length of coaxial cable which is connected to a coaxial cable connector or adapter which is affixed to the probe's body. A second portion of coaxial cable typically has one end that is supported by the probe's body and a second end that is freely suspended. The conductors at the end supported by the body of the probe are interconnected with the adapter enabling signals to be communicated from the test instrumentation to the freely suspended end of the second length of coaxial cable. A microstrip-type probe tip is commonly attached to the freely suspended end of the second portion of coaxial cable. A microstrip-type probe tip typically comprises a plurality of contacts or probe tips that are affixed to a substrate that is, in turn, affixed to the freely suspended end of the coaxial cable. Typically, one contact conducts the signal from the central conductor to a probe pad of the test structure. In addition, one or more contacts connected to the outer conductor of the coaxial cable are arranged to contact probe pads that are interconnected with the ground plane at the back surface of the wafer enabling the amplitude of the single-ended signals to be referenced to the ground potential of the DUT.

At higher microwave frequencies, the transmission efficiency of coaxial cable is substantially reduced as a result of skin effect and heating of the dielectric separating the coaxial conductors. In addition, coaxial cable adapters that can efficiently conduct signals at frequencies above 65 GHz have only recently become available and are quite expensive. Accordingly, for frequencies greater than approximately 40 GHz, it is common to utilize a waveguide to interconnect the instrumentation with the portion of the coaxial cable that supports the probe tip. A waveguide is characterized by excellent isolation between signals and very low signal loss. However, the transition from a coaxial cable to a waveguide can be expensive and difficult to execute and often results in a substantial signal loss in addition to the signal loss in the portion of coaxial cable that supports the probe tip. The present inventor considered the frequency limitations and the cost of coaxial cable components suitable for high frequencies and concluded that the transmission efficiency of a high frequency probe could be improved and the cost reduced with a waveguide probe that eliminates coaxial cable from the signal path connecting the probe's contacts to the test instrumentation.

Further, the inventor recognized that devices utilizing single ended or ground referenced signals were susceptible to poor grounding at microwave frequencies. As a result of the layering of conductive, semi-conductive and insulating materials, parasitic electrical interconnections commonly exist between parts of the devices that comprise an integrated circuit and between the devices and the substrate on which they are fabricated. These interconnections are typically capacitive and inductive in nature and the parasitic impedances between respective portions of the circuit and the ground plane are frequency dependent making the amplitude of a ground referenced signal uncertain. Referring to FIG. 9, a balanced device 100 comprises two nominally identical circuit halves 100A, 100B that are “virtually” grounded 104 at the symmetrical axis 102 of the circuit halves. A balanced device outputs a differential mode signal comprising even and odd mode components of equal amplitude and opposite phase (So +1 and So −1) 106A, 106B when stimulated with a differential mode signal comprising even and odd mode components of equal amplitude and opposite phase (Si +1 and Si −1) 108A, 108B. The virtual ground is independent of the physical ground path of the circuit and, at the operating frequency, the potential at the virtual ground does not change with time regardless of the amplitude of the stimulating signal. The virtual ground enables balanced or differential circuits to tolerate poor RF grounding better than circuits operated with single ended signals. The inventor concluded that a wafer could be probed with differential signals at microwave frequencies with a waveguide probe that incorporates neither high cost coaxial cable components nor special waveguide components.

Referring in detail to the drawings where similar parts are identified by like reference numerals, and, more particularly to FIGS. 1 and 2, a probing apparatus 20 includes a waveguide probe 22. The probe is designed to be mounted on a probe-supporting member 24 of a probe station so as to be movable to a suitable position for probing a DUT, such as an individual component or a test structure on a wafer 26. In this type of application, the wafer is typically restrained on the upper surface of a chuck 28 which is part of the same probe station. The upper surface of the chuck commonly includes a plurality of apertures (not shown) that are selectively connectible to a source of vacuum. A wafer is placed on the upper surface of the chuck and air pressure secures the wafer to the chuck's surface when the vacuum source is connected to the apertures.

The exemplary waveguide probe 22 has a port which comprises a waveguide 34 having a flanged connector 36. The flanged connector enables selective connection, through a mating flanged connector 38, to an external waveguide 40 that connects the probe to the test instrumentation 42. The flanged connector may comprise, for example, one or more flexible or rotary connectors enabling movement of the probe relative to the external waveguide and the instrumentation. The waveguide 34 is affixed to a primary support block 44 of the probe which, in the preferred embodiment shown, is suitably constructed for connection to the probe-supporting member 24. To effect connection to the probe-supporting member, a round opening 46 that is formed on the support block is snugly and slidably fitted onto an alignment pin (not shown) that projects upward from the probe-supporting member. Screws 48, inserted into each of a pair of countersunk openings 50 in the block, engage a corresponding threaded aperture in the probe-supporting member to secure the probe to the supporting member. Ordinarily an −x, −y, −z positioning mechanism, such as a micrometer knob assembly, is provided to effect movement of the supporting member relative to the chuck so that the contacts 32 of the probe can be brought into pressing engagement with the probing pads 30 of a test structure or other DUT.

Referring also to FIGS. 3, 4, and 5, a first end portion of a dielectric substrate or membrane 52 is affixed to the interior surface 54 of the wall 56 that defines the waveguide channel 57 of the waveguide 34. A second portion of the membrane projects beyond the end 58 of the waveguide's wall. One or more conductive signal traces 60A, 60B are supported on a surface of the membrane. The conductive traces 60 may be, for example, deposited on the surface of the membrane using any technique or may be otherwise affixed to or supported on the surface of the membrane. The thickness, length and configuration of the traces may be varied to optimize the performance of the probe for a particular band of frequencies to be transmitted by the probe. One end of each conductive trace 60 is conductively connected with the interior surface of the wall of the waveguide and electrically interconnects the wall of the waveguide with a respective contact 32A, 32B. The contact may include a conductive portion, such as a via portion, that passes through the substrate enabling conduction of the signals from one side of the membrane to the other. The projecting end of the membrane and portions of the contacts may formed at an angle to the upper surface of the membrane to improve the visibility of the contacts when the waveguide is arranged at an angle to surface of the chuck.

While a wide variety of cross-sections are available for waveguides, the cross-section of the waveguide channel preferably has a longer major axis or dimension (h) and a shorter minor axis or dimension (w) normal to the longitudinal axis 33 of the waveguide channel. For example, a rectangular waveguide channel is defined by a major dimension parallel to the longer sides of the rectangular channel and a minor dimension parallel to the shorter sides of the channel. Electromagnetic waves propagate in a waveguide channel by successive reflections from the inside surface(s) of the wall. A waveguide channel with unequal major and minor dimensions prevents mode rotation of the microwave signals.

The electric field is the gradient of the potential difference between points on the interior surface of the wall on opposite sides of the waveguide channel. In a waveguide channel defined by a longer major dimension and a shorter minor dimension, the potential difference is maximized at opposite sides of the waveguide channel at the midpoint or bisector of the major dimension. For example, in a rectangular waveguide, the distribution of the electric field 66 (illustrated schematically with a bracket) is maximized at the midpoint of the longest side of the rectangular waveguide channel. The field distribution and the potential difference in the waveguide channel permits a simple conductive connection for differential signals between the second ends of the conductive signal traces 60A, 60B and the interior surface of the waveguide's wall on opposite sides of the waveguide channel at the respective intersections of the bisector of the waveguide channel's major dimension. For example, the interconnections between the signal traces 60A, 60B and the wall of the waveguide is preferably at the midpoint of the longer walls of a rectangular waveguide channel. While interconnection of the traces and the wall of the waveguide at the bisection of the major axis of the channel maximizes the potential between the connections, the connections may be shifted away from the respective intersections with the wall by the bisector of the major dimension, by tilting the substrate relative to the wall or otherwise, for the purpose of matching the impedance of the probe with the DUT.

Referring to also FIG. 6, the dimensions of a waveguide suitable for the high frequency microwaves are relatively small and the availability of waveguides of suitable dimensions may be limited. A suitable waveguide 70 having a rectangular waveguide channel and a circular exterior surface may be fabricated by drilling and broaching or otherwise cutting a rectangular waveguide channel 72 in a solid rod or thick walled tube.

Referring also to FIG. 7, a suitable waveguide 74 having an elliptical channel 79 with a major dimension (h) and a minor dimension (w) may be fabricated by deforming the wall of a circular tube at opposites sides of the tube. Connecting the respective conductive signal traces 60A and 60B to the inside surface of waveguide's wall on opposite sides of the waveguide channel at approximately the bisection of the major axis (h), for example, the bisection of the longer wall of a rectangular waveguide channel, enables a simple, low loss connection for the equal amplitude, out-of-phase, differential signals that are input to or output by a differential signaling DUT.

In addition, preferably, the transition from the coplanar lines of the probe tip to the wall of the waveguide is optimized by conductively interconnecting the conductive signal traces to the wall of the waveguide at a distance (L) from the end 58 of the waveguide 34. The optimum distance (L) is typically less than one-half the wavelength of the center frequency of signals that will be transmitted in the waveguide.

The end portion of the membrane 50 that is within the waveguide channel is secured to the interior surface of the waveguide adjacent the bisection 76 of the major dimension of the waveguide channel enabling the conductive signal traces supported on the surface of the membrane to be interconnected with the waveguide's wall at the bisection of the major dimension. Supporting the conductive signal traces on the upper surface of the membrane reinforces the probe tip's structure but, as illustrated in FIG. 6, the signal traces can be supported on the lower surface of the membrane. The membrane or substrate 52 may be rigid or flexible. A flexible membrane provides resilient support for the contacts enabling both contracts to engage probe pads even if the surfaces of the probe pads are not coplanar. Further, referring to FIG. 8, a flexible membrane produces horizontal movement or scrubbing (K) by the contacts when the probe is displaced vertically after engagement of the contacts and probe pads. Scrubbing improves electrical conduction between the contact and the probe pad by promoting penetration of an insulating oxide layer that can form on the surface of the probe pads.

The waveguide probe can be simplified by leaving the end of the waveguide channel open. However, an open end of the waveguide channel permits an electric and magnetic field distribution that couples to a propagating wave in space and evanescent fields that couple to physical objects proximate the end of the waveguide. Shorting plates 78, 80 blocking portions of the waveguide channel at the end proximate the probe tip can reduce the fields proximate the end of the waveguide. The shorting plates can be arranged at an oblique angle to the longitudinal axis of the waveguide. Preferably, a first shorting plate 78, occluding a first portion of the waveguide channel above the membrane, is arranged to be perpendicular to the surface of the wafer when the probe pads are contacted to improve visibility of the contacts. A second shorting plate 80 below the membrane 52 is preferably arranged substantially parallel to the surface of the wafer when the probe pads are contacted to minimize the length of the membrane that must project from the end of the waveguide and reduce the likelihood that the waveguide will come in contact with wafer. The performance of the wafer probe can be optimized for a particular frequency band by adjusting the angles of the respective shorting plates relative to the longitudinal axis of the waveguide channel.
